Why do images need to have an image file format? There are several image file formats often involved in prepress, and what is their nature? A: The image file format determines what type of information should be stored in the file, how the file is compatible with various application software, and how the file exchanges data with other files. Since there are many image formats, you should decide what format the image should be stored according to the purpose of the image. The image file formats commonly used in design are: TIFF format: TIFF is a labeled image file used to store images composed of color channels. Its biggest advantage is that the image is not limited by the operating platform. It can be used regardless of PC, MAC or UNIX. It can save the Alpha channel and can store color separation data in a file. EPS format: EPS format is used for printing and printing, can save Duotone information, can store Alpha channel, can store path and screen information. GIF is an 8-bit format that can only express 256 levels of color. It is a common format for spreading images on the Internet.

PSD is mainly used as an intermediate transition of the image file to save the channel and layer of the image for later modification. The format is poorly versatile, and only Photoshop can use it, and few other applications support it.
JPE is both a file format and a compression method. This compression is lossy, the loss size varies, and some are too small to be recognized by the human eye.
